Molecular and Morphological Analyses Reveal Phylogenetic Relationships of Stingrays Focusing on the Family Dasyatidae (Myliobatiformes) [PDF]
PLoS ONE, 2015 Elucidating the phylogenetic relationships of the current but problematic Dasyatidae (Order Myliobatiformes) was the first priority of the current study. Here, we studied three molecular gene markers of 43 species (COI gene), 33 species (ND2 gene) and 34

Secondary predation constrains DNA-based diet reconstruction in two threatened shark species [PDF]
Scientific Reports, 2021 Increasing fishing effort, including bycatch and discard practices, are impacting marine biodiversity, particularly among slow-to-reproduce taxa such as elasmobranchs, and specifically sharks. While some fisheries involving sharks are sustainably managed,

Branching patterns of the afferent branchial arteries and their phylogenetic significance in rays (Batoidea) [PDF]
Scientific Reports, 2021 Rays of the superorder Batoidea comprise the most diverse group of chondrichthyans in terms of valid species and morphological disparity. Up to the present little agreement is observed in studies based on morphological and molecular data focused on ...

Aerial Imagery Reveals Abnormal Stingray, Taeniura lymma (Myliobatiformes: Dasyatidae), in the Central Red Sea [PDF]
Ecology and EvolutionWhile morphological abnormalities have been widely reported in batomorphs, ontogenetic deformities of the posterior pectoral fin are rare. In this paper, we present a bluespotted ribbontail ray, Taeniura lymma (Forsskål, 1775), with symmetrically ...
